Abstract

A radio frequency identification (RFID) device is described. In one implementation, there is provided a keyboard emulator; a first keyboard interface configured to receive an operative connection to a host computer, and operatively connected to the keyboard emulator; and a controller configured to receive data from at least one RFID tag; and transfer the data through the keyboard emulator and then the first keyboard interface in response to a user-initiated route instruction received by the controller, wherein the keyboard emulator converts the data to corresponding keystroke codes.

Claims

1. A device comprising:

a keyboard emulator;

a first keyboard interface configured to receive an operative connection to a host computer, and operatively connected to the keyboard emulator; and

a controller configured to

receive data from at least one RFID tag; and

transfer the data through the keyboard emulator and then the first keyboard interface in response to a user-initiated route instruction received by the controller, wherein the keyboard emulator converts the data to corresponding keystroke codes.

2. The device of claim 1 wherein the controller is configured to recognize a keyboard message received via the first keyboard interface as a user-initiated route instruction received by the controller.

3. The device of claim 1 further comprising a second keyboard interface, and wherein the controller is configured to recognize a series of one or more keystrokes received via the second keyboard interface as a user-initiated route instruction received by the controller.

4. The device of claim 1 further comprising one or more user-operable inputs configured to initiate a route instruction to the controller upon actuation by a user.

5. The device of claim 4 wherein the one or more user-operable inputs are keys on the housing of the device.

6. The device of claim 1 wherein the first keyboard interface is a USB port, a PS/2 port, a serial interface, a TCP/IP port, or a wireless interface.

7. The device of claim 1 further comprising a display, and wherein the controller is further configured to convey on the display information pertaining to a quantity of detected RFID tags for which data has been received.

8. A method of transferring radio frequency identification (RFID) data using a device, the method comprising:

receiving data from at least one RFID tag to the device; and

transferring the data through a keyboard emulator and then a first keyboard interface in response to a user-initiated route instruction, wherein the keyboard emulator converts the data to corresponding keystroke codes.

9. The method of claim 8 further comprising conveying information pertaining to a quantity of detected RFID tags for which data has been received.

10. The method of claim 8 further comprising transferring command keystrokes from the keyboard emulator through the first keyboard interface in response to a user-initiated route instruction.

11. The method of claim 8 wherein the user-initiated route instruction is a keyboard message.

12. The method of claim 8 wherein the user-initiated route instruction is initiated by an activation of a user-operable input.

13. The method of claim 8 wherein the user-initiated route instruction is initiated by receiving data for a predetermined quantity of RFID tags.

14. The method of claim 8 wherein the user-initiated route instruction is initiated by receipt of a series of one or more keystrokes.
